摘要:

反应与传递过程的耦合是众多化工过程的重要特征之一。随着过程精准调控要求的不断提高和过程强化与微化工等领域的迅速发展,传统上宏观与微观分离的反应与传递描述方式遇到了诸多挑战。拟颗粒模拟耦合软球和硬球两类分子模拟方法的优势,显著简化了分子间作用模型,极大提高了计算效率,为描述宏微观之间的介尺度上反应与传递紧密耦合的复杂现象提供了一种有效手段。本文简要回顾该方法提出的背景,阐述其基本思想,并展示和分析其在气固多相吸附和催化、气液微流动等问题中的应用前景。

Abstract:

The coupling of reaction and transport is characteristic for many chemical processes. With the ever-rising standards for precise control of the processes, and the fast development of process intensification and micro-chemical systems, the traditional framework of describing reaction and transport at micro- and macro-scales separately has faced many challenges. By integrating the advantages of hard-sphere and soft-sphere molecular dynamics simulation methods, pseudo-particle modeling has provided an effective microscopic method with significantly simplified molecular interactions and tremendously higher efficiency for describing the complexity of strong reaction-transport coupling at the meso-scale between the micro- and macro-scales. This article will briefly review the background and development of the method and demonstrate its application in gas-solid multi-phase adsorption and catalysis, gas-liquid nano-/micro-flow and so forth.

Key words: reaction-transport coupling, transport processes, multi-scale, meso-scale, pseudo-particle modeling
